LXXLD70 Datasheet
 
0.8V REFERENCE ULTRA LOW DROPOUT LINEAR REGULATOR



 
 
DESCRIPTION
 
The UTC LXXLD70 is a typical LDO with the features of very
low dropout voltage as low as 0.15V at output current 7.0A.
For normal operation, two supply voltages are necessary.
One called control voltage from other equipment can shutdown
the output voltage and it should pull and hold the voltage of EN
pin less than 0.3V. Another one is the main supply voltage whose
purpose is for main power conversion, to keep the power
dissipation low, and to make the dropout voltage lower.
Internally, in the UTC LXXLD70, there’re many functions
which can be seen in the block figure to prevent the IC from being
damaged. Internal Power-On-Reset (POR) circuit can control the
two supply voltages to prevent fault operations of the circuit; the
thermal shutdown circuit is able to protect the device from over
thermal operation, and a current limit function will keep the device
work safely under current over-loads.
The UTC LXXLD70 can be used as an ideal to provide well
supply voltage in the applications, such as front-side-bus
termination on motherboard, NB applications, front side bus VTT
(1.2V/7.0A) and note book PC applications.
